A hospital administrator wants to determine the proportion of emergency room patients that use the emergency room (ER) for non-emergency care. She randomly samples records from 350 ER patients and determines that 74 of those patients required only non-emergency care. 1. The administrator constructs a 90% confidence interval for the true proportion of all ER patients who use the ER for non-emergency care. The error bound for the proportion EBP for this confidence interval is: A. 0.036 B. 0.072 C....

A random sample of 1,175 people in a certain country were asked whether they thought climate change was a problem. The sample proportion of those who think climate change is a problem was calculated, and a 95 percent confidence interval was constructed as (0.146, 0.214). Which of the following is a correct interpretation of the interval? a) We are 95 percent confident that any sample of 1,175 people will produce a sample proportion between 0.146 and 0.214. B)We are 95...

Suppose a hospital would like to estimate the proportion of patients who feel that physicians who care for them always communicated effectively when discussing their medical care. A pilot sample of 40 patients found that 18 reported that their physician communicated effectively. Determine the additional number of patients that need to be sampled to construct a 95​% confidence interval with a margin of error equal to 3​% to estimate this proportion.
